**1. Introduction**

Diabetes Mellitus (DM) is a chronic metabolic medical condition that is diagnosed in 422 million people globally and every year 1.6 million deaths are attributed to this condition [1]. It is a disease that can lead to many other severe medical problems and affects almost all the different systems in the body. Diabetes as a result of autoimmune condition, where the pancreatic β-cells are destroyed compromising insulin production, is referred to as Type 1 Diabetes Mellitus (T1DM), while diabetes caused by several other factors including increasing insulin resistance is referred to as Type 2 Diabetes Mellitus (T2DM). As the classic symptom of diabetes is increase in circulating blood glucose, one of the important treatment criteria is focused on food consumption and the type of nutrients consumed. Several diets have been advocated to patients, in addition to life style changes such as increased physical activity and an organized exercise regimen. As carbohydrates are the main source of glucose, diets closely look at reducing carbohydrate intake followed by fat consumption. A major risk factor for developing diabetes is being obese. So many diet plans for diabetic patients focus on weight loss. We will discuss the different diets, nutritional supplements and any alternative and complementary medical choices the patients can opt for.
